WILLIAM D. NICHOLSON AND WILLIAM H. SMITH, OF GLYMERS, INDIANA.

BOILER-CLEANER.

T 0 all whom it may concern:

Be it known that we, WILLIAM D. NronoL- SON and l/VILLIAM II. SMITH,citizens of the United States, residing at Clymers, in the county ofCass and State of Indiana, have invented certain new and usefulImprovements in Boiler-Cleaners and we do declare the following to befull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to boiler cleaners, and the object of theinvention is to provide a device of this character which may have oneend thereof attached to the steam dome or other part of the boiler whereit may be in communication with the steam, and the other end attached tothe blow-oil opening so as to ell'ectually blow out or 'form a suctionwhich will draw into the blow-otl' device all the scale and mud in theboiler.

lVith this and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be described and particularly pointed out in the appended claim.

In the accompanying drawings, Figure l is a longitudinal sectional viewof the device; Fig. 2 is a transverse sectional view on the line rc.r ofFig. 1 and Fig. 3 is a transverse sectional view on the line g g of Fig.1.

Referring more especially to the drawings, 1 represents a boiler, 2 theline tubes mounted therein, and 3 the steam dome. Below the tube in thebottom of the boiler the shield, l, is supported by outstanding legs, 5,bolted to the shield and extending out from either side thereof toengage the bottom of the boiler.

6 represents the live steam pipe which is connected in any suitablemanner to the steam dome 3, or other suitable source, and has connectedto it the lead, 7, by a suitable coupling, 8, which joins the partstogether. This lead extends to the bottom of the boiler where it isjoined with one of a series ol discharge nozzles, 9, by an elbow, 10, ofthe usual construction. Each nozzle is provided. at one end with areduced or beveled edge so as to fit within the reamed-out opposite endof the nozzle, and each nozzle is secured by two U-shaped clips, 11,which pass through Specification of Letters Patent.

Application filed March 9, 1908.

] the shield, 4, and are secured by nuts, 12. threaded upon their outerends. The first nozzle, 5, is threaded into the elbow, 10, and has abeveled front end. The last nozzle projects into the reamed-out end of asleeve, 13, of the same diameter as the nozzles. This sleeve is mountedupon the shield in a manner similar to the nozzle 5, and is connected toan elbow, 14, which couples the sleeve with a connecting pipe, 15,communicatin g with the discharge or blow-oil opening. This pipe, 15, isprovided with a valve, 16, controllable to prevent the operation of thedevice, except when needed.

From the foregoing description, taken in connection with theaccompanying drawing. the construction and operation of the inventionwill be readily understood without rcquiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claim.

Having thus described our invention, what we claim new and desire tosecure by Letters-Patent, is:

In a device ol the class described, the combination with a boiler, of asteam supply pipe connected to the source of steam supply therefrom, adischarge nozzle connected to the blow-out hole of the boiler, aplurality of disconnected nozzles arranged in alinomont between thesupply pipe and the discharge pipe, an inverted \lshaped shield coveringsaid nozzles and separated therefrom, clamping devices carried by saidshield for supporting said nozzles in alinement, and a plurality of legssecured on the under side of the shield for raising the shield andsupporting the device within the boiler said legs having their innerends engaged with the nozzles so as to be held in position thereby.

In testimony whereof we have hereunto set our hands in p rescnce of twosubscribing witnesses.
